My invention relates to a hand-operated apparatus for the printing,chiefly to be used for the printing of patterns, in several colors,

on interior walls, to replace wallpaper.

The, apparatus fulfills its purpose by posto each other, every one ofthem being provided with color separately. The p'atternrolls are mountedon a loose frame which may be manipulated by hand in such a way thatwhen being passed over the surface to be printed, the rolls roll up, oneafter another. Besides, the rolls are so connected with each other, thatany one turning, makes the others turn, too. so that any turningposition of one roll corresponds to determined turning positions of theothers. For this reason, the prints of the various rolls, the latterbeing rolled up on the surface to be printed, lie in determinedpositions to each other. v

The enclosed drawings show my printing apparatus namely Fig. 3front-view,

Fig. 1 side-view, V Fig. 2 view from below,

Fig. 4: is a slight modification of the invention. v

The printing rolls 3 and three color rolls 4: are mounted, parallel toeach other, to rotate, on a frame consisting of two forks 1 and 2,connected with each other and adjustable Rolls 4 are firmly fixed totheir beams 5 and rolls 3, on the lower fork 1, and rolls l, on theupper fork 2, are placed in a way that a color roll each printing roll.

.One of the arms of fork 2 is connected with i the partbearing thehandle by a'joint 6, and

the loose ends of both forks form slits 7 in which a connectlng rod 8 isplaced, to keep the arms in the right distance, and whose middle partforms a handle. I

To put in rolls 4:, the connecting rod 8 is pulled out and the armsspread outwards around joint 6,

'One of the arms of fork 1 is connected with the part bearing the handleby ajointfi, and clamp 9, so that it may be shifted outwards, to put inrolls 3. Itis also feasible, because of the possibility to shift one-ofthe'arms of fork 1, to use printing rolls 3 of different lengths, shouldthe pattern to be printed require same.

On each end of the middle printing rolls 8- is firmly mounted a sprocket11,:- of which each is connected,-*by a driving chain 12, with a wheel,whichisfa'stened on'the beamo of one of the outer-printing rolls 3, in away that to fork 2 through shifting arms on the it may be released bymeans of a regulating screw 14.

when the three rolls are being rolled up on a surface, the apparatusbeing pulled over the surface in a straight line, while thethreeprinting rolls are touching the surface and each being provided withcolor. by its roll 4,

' the prints of the rolls'3 harmonize exactly as desired. To work withthe apparatus, onehand'holds handle and the other the handle formed bythe connecting rod 8, whereupon the print vPrinting apparatuses areknown which V have several printing rolls on the same beam,

whichare supplied with color by a color roll.

Such apparatuses I do not claim as my invention since they only serve toprint plain patterns, dots, rings and the like, and the parts of i I thepattern of various colors must beside by side. v 1 I p i I also know aprinting apparatus that has two printing rolls which are separately sup,7
